Outer Space is COLD. We're talking aproxamitly 3° kelvin. That is only 3° away from absolute zero, at which ALL activity stops, such as atoms and even electrons stop moving. [2]
Bodies in Outer Space
There are many differentiating bodies within space, most can be placed within the following groups: planets, stars, black holes.
